摘要
主要研究内容包括如下几个方面: 粘结相 Ni- Co( Ni ∶ Co = 1 ∶1 , 质量比, 下同) 与不同 N/ C 比的硬质相 Ti( C, N)( Ti N/( Ti C+ Ti N) = 0 .1 ,0 .3 ,0 .5 ,0 .7 ,0 .9) 之间的润湿规律;粘结相 Ni- Co - Mo , Ni - Co - Ta , Ni- Co - Mo - C 与硬质相 Ti( C, N) 之间的润湿情况;以及在 Ti( C, N) 硬质相中添加 Ta C, Nb C 等对润湿性的影响。研究表明,当硬质相中 Ti N/ ( Ti C+ Ti N) < 0 .5 时宜采用 Ni - Co 作粘结相, 而当 Ti N/ ( Ti C+ Ti N) ≥0 .5时,则应选择 Ni- Co - Mo - C 作粘结相更适合。
The contents of this paper include several aspects as follows, the wettability between Ni-Co binder phase and different nitrogen-to-carbon ratio of hard phases TiCN(TiN/(TiC+TiN))=0.1,0.3,0.5,0.7,0.9), the wettability between Ni-Co-Mo、Ni-Co-Mo-Ta、Ni-Co-Mo-C binder phases and TiCN hard phases, and the influence by adding TaC、NbC to TiCN hard phases. The results demonstrate that, it's suitable to choose Ni-Co binder phase when the ratio is less than 0.5, and choose Ni-Co-Mo-C binder phase when the ratio is no less than 0.5.
